On Sunday, Fergie attended TrevorLive LA, a fundraising gala by the Trevor Project, an organization that provides crisis intervention and suicide prevention services to LGBT youths.

Fashion designer and film director Tom Ford and actor and singer Kristin Chenoweth were among the night's honorees, but attention has turned to Fergie's odd behavior after she interrupted Armie Hammer, who was onstage to make some remarks about Ford.

The incident began when Fergie approached the podium and tapped Hammer on the shoulder, indicating that she wanted to speak. "I'm actually Armie Hammer, thank you," she said.

The singer then proceeded to crack a few jokes about Hammer, saying, "I'm going to win at the Academy Awards, thanks."

She was soon interrupted when someone in the audience shouted out to Hammer, to which Fergie replied, "They love you, they really do, they really love you," presumably a reference to Sally Fields' iconic Oscar speech.

After a rough start, the singer then began to talk about Ford, but she soon changed the subject and started promoting a single from her new album — and then she broke out into song.
